German submarine U-39 (1938)
Summary
German submarine U-39 was a Type IXA U-boat of the Kriegsmarine that operated from 1938 to the first few days of World War II.
She was ordered by the Kriegsmarine on 29 July 1936 as part of the re-armament program (Aufrüstung) in Germany, which was illegal under the terms of the Treaty of Versailles. The keel for U-39 was laid down on 2 June 1937, by DeSchiMAG AG Weser of Bremen. She was commissioned on 10 December 1938 with Kapitänleutnant Gerhard Glattes in command.
On 14 September 1939, just 27 days after she began her first patrol, U-39 attempted to sink the British aircraft carrier by firing two torpedoes at her. Due to a technical defect the torpedoes exploded before reaching their target. The U-39 was immediately hunted down by three British destroyers and disabled with depth charges. After the crew managed to resurface with the then sinking submarine all members were captured during the evacuation.
U-39 was the first German U-boat to be sunk in World War II.
As one of the eight original German Type IX submarines, later designated IXA, U-39 had a displacement of when at the surface and while submerged. The U-boat had a total length of , a pressure hull length of , a beam of , a height of , and a draught of . The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of for use while submerged. She had two shafts and two propellers. The boat was capable of operating at depths of up to .
The submarine had a maximum surface speed of and a maximum submerged speed of . When submerged, the boat could operate for at ; when surfaced, she could travel at . U-39 was fitted with six torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one SK C/32 naval gun, 180 rounds, and a SK C/30 as well as a C/30 anti-aircraft gun. The boat had a complement of forty-eight.
U-39 conducted only one war patrol during her entire career, as part of the 6th U-boat Flotilla.
